The Telecommunications Information Network Architecture defines an architecture for advanced service provision and intelligence in a telecommunications network environment. Due to the distributed nature of the system, there are a number of performance issues that will need to be addressed when working versions of the architecture are deployed in operational systems. Overload protection and dynamic load control in the Distributed Processing Environment is vital to ensure Quality of Service guarantees. This report presents a mechanism based on CORBA Portable Interceptors to capture detailed statistics for each object interaction in the Distributed Processing Environment, and shows how this technique can be used to measure and monitor software performance within the TINA architecture to achieve desired performance objectives. Illustrative results demonstrating the range of performance metrics collected are presented based on data collected by applying the developed technique within the South African TINA Trial
